How to prepare Sentinel-1 images stack for PSI/SBAS in SNAP

gabrielaquintana77 · February 15, 2018, 5:18pm

ah wow!!! let me make again the copy and pasted of the scripts and the run again!!!

gabrielaquintana77 · February 16, 2018, 1:05pm

Yesterday, I did ran the script again, this time

./mt_prep_gamma_snap 20160208 /sdd/RESULTADOS1 0.4 2 2 50 200

and this time, I can see that executed pscands.1.ij0

but, I think that the processed not overwrite the PATCH files!!! because this give me error when I want to plot

I readed the suggestion from @thho , so, my question is, I have to modify this script ps_plot.m or getpsver?

Hi,
You need to delete Break commands in some .m files. I will send you my runnable matlab folder. But ı am not at home at this weekend. I will send next Monday.

Hi @Fikretjfm

I did run again, with the folder that you send me, and have the same error, the pscands file are empty

Please I need help with this

Thanks for advance

Hi @gabrielaquintana77,

If your .ij files are still empty, it is about running mt_prep_gamma_snap step with wrong script. I am adding you my mt_prep_gamma_snap script try it again. You need to handle with .ij files error first. Do not try stamps step without getting .ij files. And it is related to master.lat and master.lon files in your geo folder. Could you show me your geo folder with files sizes? First show me folder and if it is ok, try following step.

Also I added my mt_… script that works fine for me. Just you need to change at the and of the script with starting grep:
grep -rl ‘/cygdrive/?’ *.txt | xargs sed -i ‘s+/cygdrive/f+F:+g’
grep -rl ‘/cygdrive/?’ *.out | xargs sed -i ‘s+/cygdrive/f+F:+g’
grep -rl ‘/cygdrive/?’ *.in | xargs sed -i ‘s+/cygdrive/f+F:+g’
The question marks is your drive, if you work under /c write c for question marks. Also the second f+F should be c+C. For example like that:
grep -rl ‘/cygdrive/c’ *.txt | xargs sed -i ‘s+/cygdrive/c+C:+g’
grep -rl ‘/cygdrive/c’ *.out | xargs sed -i ‘s+/cygdrive/c+C:+g’
grep -rl ‘/cygdrive/c’ *.in | xargs sed -i ‘s+/cygdrive/c+C:+g’

Hi @Fikretjfm

This is the content from my geo folder

Fikretjfm · February 20, 2018, 2:56pm

Hi
We finally find the error. There should be master.lat and master.lon coordinate files. Therefore your .ij files are empty. Export .lat .lon files into geo folder. There are so many explanation exporting them in forum.

Ok Fikret,

I am resolving this, when I end this step I will go run again the script

Thanks for your support

gabrielaquintana77 · February 22, 2018, 5:12pm

Hi @Fikretjfm

One question, the results that I obtained in the export (/diff0, /geo, /dem, /rslc) they have to be in same folder of results with PACTH 1, PACTH 2, PACTH 3 and PACTH 4???

Fikretjfm · February 22, 2018, 5:16pm

No not need

SteffanDavies · February 23, 2018, 4:58pm

Is there an updated workflow for this procedure? I will probably make and share a step by step video if I can replicate good results.

ABraun · February 23, 2018, 7:49pm

good idea actually!
I tried to compile the latest findings in this post: About the STaMPS category

thho · February 26, 2018, 1:37pm

@SteffanDavies, have a look here, a video would be great!

mengruizu · March 1, 2018, 12:40pm

does anyone know how to solve this problem? thanks.
ps_plot(‘v’) ps_plot(‘d’) and ps_plot(’…’) shows error setting property 'PlotBoxAspectRatio ’ of class ‘Axes’ : input values must be positive finite numbers.

Dear ABraun Sir,
I have installed StaMPS under cygwin. and become to export to StAMPS from Snap as follows.

and

then I tried both mt_prep_gamma and mt_prep_gamma_snap both with full path also.
But it did not work. and I typed csh also in Cygwin, but no difference happen to me.
Would you please help me to go ahead.

Dear FeiLiu
I used windows only. I am using windows 10 pro.
In my case, mt_prep_gamma is not working. either I do it the wrong way. I tried mt_prep_gamma and mt_prep_gamma_snap both with full path and without the full path.
I would like to finish my project for measurement of the rate of displacement so please help me.
I install snaphu also before staMPS. It was working properly.

ABraun · March 6, 2018, 11:54am

don’t use Windows for this - too many error sources and nobody can probably tell you where exactly they are.
